Yep. Answered my question with a quick search. This is the most recent data on a State by state basis. From the Arkansas page:
Prisons
The Arkansas Department of Corrections did not respond to either informal inquiries or a formal request under the Arkansas Freedom of Information Act § 25-19-101 et seq. for its policy on nonemergency involuntary administration of psychotropic medication.
Upon further investigation, some information about Arkansas’s policy is provided in cases in which inmates challenged the administration of medication over objection while they were in prison. A description of the Arkansas policy that was in place in 1993 is described in Walton v. Norris, 59 F.3d 67 (8th Cir. 1995):
if an inmate objected to taking medication prescribed by a treating psychiatrist, and the psychiatrist believed that the inmate suffered from a mental disorder and was gravely disabled or likely to harm himself, others, or property, then the medication could be administered involuntarily. The inmate, however, was entitled to a hearing before the Mental Health Review Committee. Arkansas Department of Correction Policy No. 275. In this case, the committee unanimously found that Walton suffered from paranoid schizophrenia, that he had become violent when taken off of his medication in the past, and that mandatory injections were needed to prevent him from becoming psychotic again.
The court upheld the policy as it applied to the plaintiff, but by the time the decision was issued in 1995 the policy had been modified. Changes in the policy were not provided. (Id. at note 4). More recently an inmate brought suit against AR DOC alleging he was involuntarily medicated without any hearing in violation of the AR DOC policy, Hernandez v. Molden, No. 5:09-cv- 00328-JLH-JTK (Eastern District Court of Arkansas). The plaintiff, Hernandez, could not produce a copy of the policy but asserted that the policy was described in another case, Doby v. Hickerson, 120 F.3d 111 (8th Cir. 1997). At the time the Doby case was decided, the policy required a hearing and cited Washington v. Harper. According to an order issued by the judge in in the Hernandez case in April 2012, the attorney for the AR DOC was unaware of any policy concerning involuntary medication of inmates. The court provided an opportunity for AR DOC to address the issue of applicable policies in its summary judgment motion.
Jails
State law does not prohibit Arkansas county jails from administering medication involuntarily on a nonemergency basis. Therefore, county jails could use a Washington v. Harper administrative proceeding to authorize involuntary medication for an inmate who is suffering from a mental disorder, is gravely disabled, or poses a likelihood of serious harm to self or others. Based on survey information, however, Arkansas jails instead petition the court for an order to medicate an inmate involuntarily. Court orders are not used frequently.
